A portion from this year’s proceeds – up to $500,000 – will support veteran organizations affected by recent natural disasters in the U.S., including a $300,000 commitment to Team Rubicon, a veteran-led disaster relief group.

“Stand Up for Heroes is an opportunity for us all to put aside our differences and honor those who have, and continue to sacrifice so much for all of us, Bob Woodruff, ABC News correspondent and co-founder of the Bob Woodruff Foundation, said in a statement. “The power of coming together is even clearer as we reflect on Hurricanes Harvey and Irma where we were proud to see veterans stepping up as a force for good amid tragedy.”

Stewart also appeared at the 2016 Stand Up for Heroes, alongside Bruce Springsteen and comedy giants Jerry Seinfeld, Louis C.K. and Jim Gaffigan.
